Getting email using ACAccount for Facebook iOS 7 - ios

Question

First of all, I don't want to use Facebook SDK, so I managed to do this, which is working, but I don't know how to retrieve user's email, even though it is on my permissions request.
ACAccountStore *account = [[ACAccountStore alloc] init];
ACAccountType *accountType = [account accountTypeWithAccountTypeIdentifier:accountTypeName];
NSDictionary *options;
if ( [accountTypeName isEqualToString:ACAccountTypeIdentifierFacebook]){
options = #{
ACFacebookAppIdKey: #"601517946570890"
,ACFacebookPermissionsKey: #[#"email"]
};
}
[account requestAccessToAccountsWithType:accountType options:options completion:^(BOOL granted, NSError *error)
{
if (granted == YES)
{
NSArray *arrayOfAccounts = [account accountsWithAccountType:accountType];
if ([arrayOfAccounts count] > 0)
{
_account = [arrayOfAccounts lastObject];
NSDictionary *dict = #{
#"name": [_account userFullName] == nil ? [_account username] : [_account userFullName],
#"account_id": [_account identifier],
#"email": #"??"
};
NSLog(#"account info: %#",dict);
}
}
}];
there is no property on ACAccount that returns user e-mail, so I tried to find if it had to be done via SLRequest and couldn't find it.
Is it possible?

In order to get the user's email address from Facebook, you have to use the Graph API to query the current user using the Social framework:
SLRequest *request = [SLRequest requestForServiceType:SLServiceTypeFacebook
requestMethod:SLRequestMethodGET
URL:[NSURL URLWithString:#"https://graph.facebook.com/me"]
parameters:nil];
request.account = _account; // This is the _account from your code
[request performRequestWithHandler:^(NSData *data, NSURLResponse *response, NSError *error) {
if (error == nil && ((NSHTTPURLResponse *)response).statusCode == 200) {
NSError *deserializationError;
NSDictionary *userData = [NSJSONSerialization JSONObjectWithData:data options:0 error:&deserializationError];
if (userData != nil && deserializationError == nil) {
NSString *email = userData[#"email"];
NSLog(#"%#", email);
}
}
}];

Now you need to pass param in GET request. by default only ID & name.
NSDictionary *param = #{#"fields":#"email,name"};
SLRequest *request = [SLRequest requestForServiceType:SLServiceTypeFacebook
requestMethod:SLRequestMethodGET
URL:[NSURL URLWithString:#"https://graph.facebook.com/me"]
parameters:param];
